This invention relates to a windowframe having a displaceable jamb section to permit the removal of the lower and upper sash withmay Vbe clearly understood I have shown; a

out displacing any of the stopsf 5 'The main object is to yieldingly support the displaceable jamb` section in such manner that it may be sprung laterally into the sash weight housing a suiicient distance to permit the sash to be moved endwise into the open- 10 'ing formed by such displacement for withdrawingA its opposite side from between the stops and parting strips and then moved in-` wardly and laterally in a reverse direction thereby displacing the sash from the frame.

vIn other' words, I have sought to support the displaceable jamb 'section by means of 4a looped spring having its upper end secured to the overlying portion of the jamb and its o lower end provided with a vertically elongat- '20 ed-loop adaptedto interlock with a staple on the adjacent upper end of the movable jamb section whereby said sectionmay be displaced outwardly and laterally against the action'V Y of the spring and, then moved `downwardly o until limited bythe engagement of the staple with the loweI` endcof the loop thereby aording ample clearance'forreceiving the adja-v cent edge of the sash when vremoving the same from the window frame. j

Another object is to provide metallic anchorage forthe sash rvcord 'for insertionv into the sockets ofthe opposite side edges of the sash.

"Other objects andv uses willbe brought out in thefollowing description. In the drawings l Figure l is an inner face view, partlyrin section of one sideof the window frame and:

Asillustrated, in order that the invention portion of a window 'frame and portions of the lower andupper sash 2f-and- -3-. The frame `-l-"gis provided with for receiving thesash weights, not shown,

except that a portion -6`-1 ofyone of the j ambs for theV lower sash is displaceable outwardly toV form an opening tythrough which the' lower and upper sash-"2% and '-3-fmay be moved laterally 'a limited distance sufficient to withdraw their opposite sides fromengage ment with theadjac'ent stops;

right edge of the sashj from-v between the* l stop -8- and parting strip 9j-1 after which the right hand edge of thev sash may be vdrawn to the position shown by dotted lines in Figure 4 and then drawn laterally to the right to withdraw the same from the opening -6-' thus completing the removal Vcasing 1- as shown by dotted lines in Figure`4 the upper sa'sh may be lowered to the level of' the' opening v-6- andv its left" hand drawn forwardly into registration with said opening and then moved' laterally thereinto lto withdraw its opposite upright edge `from between the parting strip #9% and stop' -8- whereupon the right hand upper edge of .the sash -3 may bedrawn'inwardly to about the positionshown bydotted lines-n Figure 4 thuspermtting the sash -f3-- to' Figure 4'Vfr`omrthe openingef. Y

The lower e'ndofv the movable j amb section --G- and adjacent'upperA edge ofthe liXed j amb section-ll-are rabbeted transversely to *form` flanges ,-'-12 and -12- .adapted to overlap upon each other when the jamb sec- 13G-,Withdrawn laterallyto the right hand Y of i* tion f6- is in'operativey position.

kFor example, when the lower end ofthe section -6- is displaced from the'lixed'section l1`- it drops by its own weight along the loop 14"-- unt'illimi-t'ed by the engagement of the staple l5- with the lower end of the loop. f Y

Suitable means is provided for holding the lower end oi" the section -'-6-- against outward displacement when in its operative vpos-ition and for this purpose a screw -fl is; secured-.tol theinner face of the'l lower' end vor the'section -6--V and is provided withan ce1 Ycentric head -`-16-'f movable into' and out of engagement with the innerfaceloftlie Vadjashow'n more clearly in Figure 2.

It is understoodyof course,.that' when the sash: are brought i into.` registration with, the

- opening ,f-e' the sash weights attachedin the usualH manner* to' cords' --e-,Figure's l and'v 5, will be drawn'upwardly` out of the path of movement of the jamb section to" permitsthf latte/Mel be readily displaced outwardlyl e upwardly from the socket -ato receive the cord. Y i

The anchor -a-f may be made of sheet metal or of cast metal as may be desired for strength and durability but is hollow so that the end of the oord may be carried in a knot and inserted therein after passing the end of the cord through an opening -A- in the4 upper side thereof, the outer end as 6M of the anchor being closed and substantially smooth to register with the outer edge of the sash -2- when the anchor is inserted in the socket -a-.

What I claim is: Y Y

A frame for window sash, a window jamb having an opening-therein of suflioient size to permit the adjacent portion of the sash to pass edgewise therethrough, a jamb section normally filling said opening and displaeeable outwardly therefrom, a leaf spring having its upper end secured to affixed portion of the jamb above said opening land its lower end
